ABSTRACT:
The present invention relates to a television system using a pickup tube performing an oscillatory scan. On reception the picture restoration device uses a receiving tube which performs a linear restoration, but with a line frequency which is double the scan frequency. In addition, the signal supplied for the pickup tube is processed on reception by two separate processing channels. The two channels respectively supply first and second signals respectively corresponding to the low part and the high part of the receiving tube input signal spectrum. This input signal is then reconstituted by means of an analog mixer. This leads to a much better definition than that obtained with existing television systems.
